存储容器
存储容器是存储池中可用存储的子集(请参见创建存储容器)。存储容器是在存储池中创建的，用于存放虚拟机使用的虚拟磁盘(vDisks)。
压缩
在存储容器上启用压缩功能。压缩可以节省物理存储空间，提高I/O带宽和内存使用——这可能对整体系统性能有积极的影响。
当写入Extent Store (SSD + HDD)时，内联压缩将压缩连续的数据流或大的I/O大小(>64K)。
脱机压缩最初将按正常方式(在未压缩状态下)写入数据，然后利用策展器框架压缩数据集群范围。
下图解释了内联压缩如何与DSF写I/O路径交互:
重复数据删除
重复数据删除通过整合Nutanix存储上的重复数据块来减少空间占用。可以只启用缓存重复数据删除功能，也可以同时启用缓存重复数据删除功能和容量重复数据删除功能。
此外，在开启重复数据删除功能的集群中，控制虚拟机需要配置更多的RAM:
缓存重复数据删除:24gb RAM
重复数据删除容量:32gb RAM
